Shutter Island

"After she tried to kill herself the first time, Dolores told me she... she had an insect living inside her brain. She could feel it clicking across her skull, just... pulling the wires, just for fun. She told me that. She told me that but I didn't listen. I loved her so much."

Nurse Marino: "She was in a group therapy session."
Teddy Daniels: "Anything unusual occur?"
Nurse Marino: "Define 'unusual'."
Teddy Daniels: "Excuse me?2
Nurse Marino: "This is a mental institution, Marshall. For the criminally insane. Usual isn't a big part of our day."

George Noyce: "You wanna uncover the truth? You gotta let her go."
Teddy Daniels: "I can't."
George Noyce: "You have to let her go!"
Teddy Daniels: "I can't! I can't!"
George Noyce: "Then you'll never leave this island."

Dr. Jeremiah Naehring: "Did you know that the word 'trauma' comes from the Greek for 'wound'? Hm? And what is the German word for 'dream'? Traum. Ein Traum. Wounds can create monsters, and you, you are wounded, Marshall. And wouldn't you agree, when you see a monster, you... you must stop it?"
Teddy Daniels: "Yeah... I agree."

"Sanity's not a choice, Marshall. You can't just choose to get over it."

"Why are you all wet, baby?"

"This is a game. All of this is for you. You're not investigating anything. You're a fucking rat in a maze."

Teddy Daniels: "I had a friend. I was with him yesterday, but we got separated. Have you seen him?"
Rachel 2: "Marshall... you have no friends."
